The current, official title in German is Bundeskanzler(in), which means "federal chancellor", and is sometimes shortened to Kanzler(in).
The 8th and current chancellor is Angela Merkel, who is serving her fourth term in office.
She is the first female chancellor.[3]

During the various eras, the role of the chancellor has varied. From 1867 to 1918, the chancellor was the only responsible minister of the federal level. He was installed by the federal presidium (i.e. the Prussian king; since 1871 called Emperor). The Staatssekretäre were civil servants subordinate to the chancellor. Besides the executive, the constitution gave the chancellor only one function: presiding over the Federal Council, the representative organ of the states (together with the parliament the law maker). But in reality, the chancellor was nearly always installed as minister president of Prussia, too. Indirectly, this gave the chancellor the power of the Federal Council, including the dissolution of parliament.

Although effective government was possible only on cooperation with the parliament (Reichstag), the results of the elections had only an indirect influence on the chancellorship, at most. Only in October 1918, the constitution was changed: it required the chancellor to have the trust of the parliament. Some two weeks later, Chancellor Max von Baden declared the abdication of the emperor and ceded power illegally to the revolutionary Council of People’s Delegates.

According to the Weimar Constitution of 1919, the chancellor was head of a collegial government. The chancellor was appointed and dismissed by the president, as were the ministers, upon proposal by the chancellor. The chancellor or any minister had to be dismissed if demanded by parliament. As today, the chancellor had the prerogative to determine the guidelines of government (Richtlinienkompetenz). In reality this power was limited by coalition government and the president.

When the Nazis came to power on 30 January 1933, the Weimar Constitution was de facto set aside. After the death of President Hindenburg in 1934, Adolf Hitler, the dictatorial party leader and chancellor, took over the powers of the president. The new official title became Führer und Reichskanzler (meaning "Leader and Chancellor of the Realm").

The 1949 constitution gave the chancellor much greater powers than during the Weimar Republic, while strongly diminishing the role of the president. Germany is today often referred to as a "chancellor democracy", reflecting the role of the chancellor as the country's chief executive.

Since 1867, 33 individuals have served as heads of government of Germany, West Germany, or Northern Germany, nearly all of them with the title of Chancellor.

In 1559, Emperor Ferdinand I established the agency of an imperial chancellery (Reichshofkanzlei) at the Vienna Hofburg Palace, headed by a vice-chancellor under the nominal authority of the Mainz archbishop. Upon the 1620 Battle of White Mountain, Emperor Ferdinand II created the office of an Austrian court chancellor in charge of the internal and foreign affairs of the Habsburg Monarchy. From 1753 onwards, the office of an Austrian state chancellor was held by Prince Kaunitz. The imperial chancellery lost its importance, and from the days of Maria Theresa and Joseph II, merely existed on paper. After the dissolution of the Holy Roman Empire, Prince Metternich served as state chancellor of the Austrian Empire (1821–1848), likewise Prince Hardenberg acted as Prussian chancellor (1810–1822). The German Confederation of 1815-1866 did not have a government or parliament, only the Bundestag as representative organ of the states.

In the now defunct German Democratic Republic (GDR, East Germany), which existed from 7 October 1949 to 3 October 1990 (when the territory of the former GDR was reunified with the Federal Republic of Germany), the position of chancellor did not exist. The equivalent position was called either Minister President(Ministerpräsident) or Chairman of the Council of Ministers of the GDR(Vorsitzender des Ministerrats der DDR). (See Leaders of East Germany.)

Under the constitution of 1 January 1871, the king had additionally the title of Emperor. The constitution still called the chancellor Bundeskanzler. This was only changed in the new constitution of 16 April 1871 to Reichskanzler. The office remained the same, and Bismarck was not even re-installed.

In the 1871 German Empire, the imperial chancellor (Reichskanzler) served both as the emperor's first minister, and as presiding officer of the Bundesrat, the upper chamber of the German parliament. He was neither elected by nor responsible to Parliament (the Reichstag). Instead, the chancellor was appointed by the emperor.

The federal level had four organs:

the king of Prussia in his federal constitutional role as bearer of the Bundespräsidium, since 1871 with the title of emperor

the federal council (Bundesrat), consisting of representatives of the federal states and presided over by the chancellor

Technically, the foreign ministers of the empire's states instructed their states' deputies to the federal council (Bundesrat) and therefore outranked the chancellor. For this reason, Prince Bismarck (as he was from 1871 onwards) continued to serve as both prime minister and foreign minister of Prussia for virtually his entire tenure as chancellor of the empire, since he wanted to continue to exercise this power. Since Prussia controlled seventeen votes in the Bundesrat, Bismarck could effectively control the proceedings by making deals with the smaller states.

The term chancellor signalled the seemingly low priority of this institution compared to the governments of the German states, because the new chancellor of the federal empire should not be a full-fledged prime minister, in contrast to the heads of the states. The title of chancellor additionally symbolized a strong monarchist, bureaucratic, and ultimately antiparliamentary component, as in the Prussian tradition of, for instance, Hardenberg.

In both of these aspects, the executive of the federation, and then empire, as it was formed in 1867 and 1871, was deliberately different from the Imperial Ministry of the revolutionary years 1848/49, which had been led by a prime minister elected by the National Assembly.

In 1871, the concept of the federal chancellor was transferred to the executive of the newly formed German Empire, which now also contained the South German states. Here too, the terms of “chancellor” and “federal agency” (as opposed to “ministry” or “government”) suggested an (apparent) lower priority of the federal executive as compared to the governments of the federal states. For this reason, neither the chancellor nor the leaders of the imperial departments under his command used the title of Minister until 1918.

The constitution of Germany was altered on 29 October 1918, when the parliament was given the right to dismiss the chancellor. However, the change could not prevent the outbreak of a revolution a few days later.

On 9 November 1918, Chancellor Max von Baden handed over his office of chancellor to Friedrich Ebert. Ebert continued to serve as head of government during the three months between the end of the German Empire in November 1918 and the first gathering of the National Assembly in February 1919, but did not use the title of Chancellor.

The office of chancellor was continued in the Weimar Republic. The chancellor (Reichskanzler) was appointed by the president and was responsible to the parliament.

Under the Weimar Republic, the chancellor was a fairly weak figure. Much like his French counterpart, he served as little more than a chairman. Cabinet decisions were made by majority vote. In fact, many of the Weimar governments depended highly on the cooperation of the president, due to the difficulty of finding a majority in the parliament.

Adolf Hitler was appointed chancellor of Germany on 30 January 1933 by Paul von Hindenburg. Upon taking office, Hitler immediately began accumulating power and changing the nature of the chancellorship. After only two months in office, and following the burning of the Reichstag building, the parliament passed the Enabling Act giving the chancellor full legislative powers for a period of four years – the chancellor could introduce any law without consulting Parliament. Powers of the chancellor continued to grow until August 1934, when the incumbent President Paul von Hindenburg died. Hitler used the Enabling Act to merge the office of chancellor with that of the president to create a new office, "the leader". Although the offices were merged, Hitler continued to be addressed as "Führer und Reichskanzler" indicating that the head of state and head of government were still separate positions, albeit held by the same man. This separation was made more evident when, in April 1945, Hitler gave instruction that upon his death the office of leader would dissolve and there would be a new president and chancellor. On 30 April 1945, when Hitler committed suicide, he was briefly succeeded as chancellor by Joseph Goebbels, as dictated in Hitler's will and testament. With Goebbels following Hitler's suicide with his own, the reins of power passed to Grand Admiral Karl Dönitz as president of Germany. Dönitz, in turn, appointed conservative Count Schwerin von Krosigk as head of government with the title “Leading Minister”.

The 1949 German constitution, the Basic Law (Grundgesetz), invests the chancellor (German, Bundeskanzler) with broad powers to initiate government policy. For that reason, some observers refer to the German political system as a "chancellor democracy". Whichever major party (CDU/CSU or SPD) does not hold the chancellorship usually calls its leading candidate for the federal election "chancellor-candidate" (Kanzlerkandidat). The federal government (Bundesregierung) consists of the chancellor and his or her cabinet ministers.

The chancellor's authority emanates from the provisions of the Basic Law and in practice from his or her status as leader of the party (or coalition of parties) holding a majority of seats in the Bundestag (federal parliament). With the exception of Helmut Schmidt, the chancellor has also been chairman of his or her own party. This was the case with Chancellor Gerhard Schröder from 1999 until he resigned the chairmanship of the SPD in 2004.

The German chancellor is officially addressed as "Herr Bundeskanzler" if the chancellor is a man. The current holder of this office, Angela Merkel, considered to be the planet's most influential woman by Forbes Magazine, is officially addressed as "Frau Bundeskanzlerin", the feminine form of the title. Use of the mixed form "Frau Bundeskanzler" was deprecated by the government in 2004 because it is regarded as impolite and was seen as a way of acknowledging Merkel's future leadership.[4]

^ She is known in German as Bundeskanzlerin. Bundeskanzlerin is a grammatically regular formation of a noun denoting a female chancellor, adding "-in" to the end of Bundeskanzler, though the word was not used officially before Merkel.
